PI6CX201A
25MHz Jitter Attenuator
Description
The PI6CX201A is composed of a phase-locked loop with
integrated VCXO oscillator for use in the clock jitter attenuation
applications. It is optimized for use with a SaRonix-eCera^™
crystal of 25MHz, and has typical output phase jitter less than
350fs (RMS).
